IMPROVEMENT IN LUBRICATINGjDEVIGE.

ette .gitana tratta tu in itat Entert htutti ma mating tutt tf tte am.

Be it known that we, BENJAMIN H. REYNOLDS, of Canterbury, in the county of Windham, and State of Connecticut, and JOHN. BACHELDER, of Norwich, county of New London, and State aforesaid, have invented a new and improved Device for Lubricating Bearings of Machinery and Shafting; and wc do hereby declare that the following is a full and exact description of thc construction and operation of the saine, reference being had 'to the annexed drawings, making a part of this specification, in which'- Figure 1 is a plan view, with the hood removed, Figure 2 a longitudinal section parted through the centre ofthe shaft vertically, and Figure 3 a transverse section parted through the centre of the lubricating-Wheel. a represents the shaft, supported in bearings 6, to which is attached the oil-reservoir c c. cl represents the lubricating-wheel, which, when used on lines of shafting, is fitted loosely on the shaft, and made to revolve with it by means of the pin e, setin the shaft at the end of the hub, in the direction the shaft expands, and projecting intd the groove in its hub. The hub should be long enough .to keep the pin in the groove during the extremes of expansion and contraction; the object of this arrangement being to allow the p lubricating-Wheel d to keep its relative position when thc shaft expands or contracts; but"1 on short shafts in machinery, saiv-arbors, 85o., we shrink it on to the shaft, which provides a substitute for collars or shoulders on the shaft, to prevent a longitudinal motion. Y i

The conducting-troughfi set nea-r and receives oil from the periphery of tho lubricating-wheel d, carried up and thrown o' by centrifugal force, and returns it to the journal-bearings through the tubes g g. When bearings are provided each side of the lub1icating-wheel, the troughfhas a partition at the centre of the Wheel, which causes a portion of the oil to flow to each bearing. The walls 7L h, running longitudinally on the edges of the reservoir, and rising above the centre of the shaft, prevent any ovcriiow of oiliraised by thc lubricatingwheel. The hood covers the whole box, excluding Boating dust in thc room, and intercepting surplus oil thrown 0E by centrifugal force.

i jj represent wipers made of iicxble cords or their equivalents, drawn diagonally across the shaft, with an inclination towards thc lubricating-wheel d, in the direction it is running, to prevent oil lowing on the shaft beyond the reservoir. l Y

Having explained the object for whichthe several parts arc designed, we will proceed to show the effect I. when put in operation. l l Oil is/placed in the reservoir ciu 'quantity sufficient to touch the periphery of the lubricating-wheel d. The shaft a being driven at thc requisite speed by power communicated by the belt on the pulley la, the oil is thrown up by centrifugal force, and caught by the conducting-trough fpand discharged upon the bearings through the tubes y g and holes in the caps of the boxes. This oil and the overflow drop into thc reservoir c, through the openings c', making the operation continuous.

What we claim, and desire to secure by Letters Patent, is- 1. The wipersjj. 2. The arrangement of the pin c and `groove inthe hub of the lubricatingwheel d, to provide for expansion and contraction.
